IPC: F02M41/14
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a distributor type fuel injection pump which suppresses the cost of production without installing a fuel pressure measuring hole anew for a fuel gallery. SOLUTION: A mounting member 50 is screwed tight in a distribution head 11 after screwing a nut 14 tight in a distribution rotor 13 via a through hole 29. After the assembly of a fuel injection pump 10 is over, a connecting member 51 of a fuel pressure measuring instrument 60 is screwed in this mounting member 50, and the fuel injection pump 10 is operated, whereby fuel pressure in a fuel gallery 15 is measurable by the fuel pressure measuring instrument 60 through a fuel passage 28 and a communication passage 50a. After the fuel pressure measurement of this fuel gallery 15, the mounting member 50 is plugged, blocking up a communicating path 50a. Since the through hole 29 for inserting the nut 14 is utilized, there is no need to install a new through hole for fuel pressure measuring of the fuel gallery 15.  Therefore, manhours for processing the through hole and parts to block up it are unnecessary.

Abstract: PURPOSE:To assure the stable high dielectric breakdown voltage by a method wherein the growth of depletion layers is accelerated by the effects of field plate and research structure while the same conductivity type layer in high impurity concentration is provided below the end of said plate through the intermediary of an insulating layer. CONSTITUTION:A conductive layer wherein a contact hole 31 is in contact with a p<+>region 2 (the second region) becomes a field plate 4 while a depletion layer 10 extends from the rear side of the conductive layer. Besides, another depletion layer 20 formed in research structure extends in the side near a PN junction 52 between an n region 1 and a p layer 6 in low concentration in contact with the n region 1. The dielectric breakdown voltage is stabilized not affected by any surface state by the actions of these two depletion layers 10, 20 while the ends of depletion layers 10, 20 are kept away from the PN junction 51 to moderate the electric field impressed on the PN junction 51 under voltage in the reverse direction. Furthermore, an n<+>region 7 in impurity concentration higher than that in the n region 1 is formed below the end of the plate 4 while the depletion layer 10 stops in this n<+>region 7 so that the electric field may not concentrate in the region 7 in low resistance causing no dielectric breakdown in this part.

IPC: B22D11/10
Filed: 1984-11-10
Abstract: PURPOSE:To make usable the electric current of a commercial frequency and to reduce the initial cost of an electromagnetic stirrer for a molten steel in a casting mold in a continuous casting device by inserting the electromagnetic stirrer onto the nozzle of a tundish. CONSTITUTION:The molten steel in the tundish 1 is poured from the nozzle 1a into the mold 2 for continuous casting and is cooled by a cooler 6 to form a steel ingot 9 which is gradually drawn from the mold 2 by drawing rollers 7. The unsolidified molten steel 8 in the casting mold is electromagnetically stirred to prevent the component segregation by which the ingot 9 having good quality is produced. The electromagnetic stirrer 10 inserted onto the nozzle 1a of the tundish acts directly on the molten steel without the attenuation of the magnetic flux density by the material of the mold 2 and therefore the current of 50-60Hz commercial frequency is usable as it is without modulation to a low frequency of 2-10Hz and therefore the power source installation of the extremely smaller capacity is required for the electromagnetic stirrer.
